This is how I check SSL Certs in my code.
I'm validating only CAcert certificats. But you can easily replace the certificate by the root cert from Go Daddy.

It's very easy and safe on API14+ (maybe since 11+).
There is some extra work to make it run on older API levels.
Basically I run my own checks on API<14 with the implementation found here: Validate X509 certificates using Java APis
